JOSEPH NAPOLEON. Seville. 4 reales. 1812 could be about 1. LA.

Catalogs: Cy14680 and it does not cite the overdate. HG and A&C also do not cite it.

Slightly cleaned. Metal somewhat lumpy. MBC-/MBC.

A questionable overdate would be very rare.

Are there any overdates on the 4 reales of José Napoleón?
Yes, although they are extremely rare, there are documented examples of overdated 4 reales coins of Joseph Bonaparte, especially in the mintings of the Seville mint. The most recognized overdate is 1812/0 (year 1812 over 1810), and the variant 1812/1 (1812 over 1811) has also been documented.

Examples and references

Seville, 1812/0 and 1812/1 (LA):

Examples have been auctioned with the date 1812 clearly superimposed on a 0 or a 1, indicating the reuse of dies from previous years. These pieces are very rare and sought after by advanced collectors.

The main catalogs and auction houses usually mention the rarity of these variants, although some classic catalogs do not explicitly mention them, which increases their interest and value in the specialized market.
